The channel is configured to hold a second signal conductor of a second electrical cable therein in electrical engagement with the first signal conductor such that the first and second signal conductors are electrically interconnected. The second electrical cable has a greater diameter than the first electrical cable. A ground shield external to the housing such that the ground shield extends at least partially around the first and second signal conductors. The ground shield is electrically connected to electrical ground conductors of the first and second electrical cables.

BACKGROUND

The subject matter herein relates generally to electrical cables that interconnect various electrical devices.

Electrical cables and connectors are used to transmit data in various industries. The electrical cables span the distance between the electrical devices to provide electrical paths between the electrical devices. The electrical connectors terminate the electrical cables and mate with complementary connectors of the electrical devices to interconnect the electrical devices via the electrical pathways provided by cables.

The termination interface of some connectors where the connector terminates multiple cables may have a relatively high density of electrical connections and therefore a relatively tight grouping of the cables, for example because of the small form factor and/or number of signal paths of many contemporary connectors. The termination interface of some connectors therefore may only accommodate electrical cables up to a certain diameter in size. In other words, the termination interface of some connectors may only accommodate relatively small diameter cables. But, such small diameter cables may not be suitable for spanning some distances between electrical devices because of the loss rate of the small diameter cable. Specifically, the loss rate for cables that have a sufficiently small diameter to fit within the termination interface of the connector may be unacceptably high. Conversely, larger diameter cables that have acceptable loss rates for the given distance between the electrical devices are too large to be grouped within the termination interface of the connector.

Accordingly, a need remains for a lower loss electrical cable that can be terminated to a connector having a termination interface with a relatively high density of electrical connections.

DETAILED DESCRIPTION

FIG. 1 is a perspective view of an embodiment of an electrical connector assembly 10. The assembly 10 includes an electrical connector 12, electrical cables 14, electrical cable splices 16, and electrical cables 18. The electrical connector 12 is configured to mate with a complementary electrical connector 20 that is mounted to one or more other electrical cables (not shown) or directly to an electrical device 22 as is shown in the exemplary embodiment. The cables 14 are terminated to the connector 12 (i.e., the connector 12 terminates, or is terminated to, the cables 14). The electrical cable splices 16 electrically connect the cables 18 to corresponding cables 14 to provide electrical pathways between the electrical device 22 and another electrical device 24. As will be described below, the cables 18 have diameters larger than diameters of the cables 14. Each electrical device 22 and 24 may be any type of electrical device. Each of the cables 14 may be referred to herein as a “first electrical cable”, while each of the cables 18 may be referred to herein as a “second electrical cable”.

The connector 12 includes a housing 26 that holds contact modules 28. The contact modules 28 hold signal contacts (not shown) and ground contacts (not shown) that extend along a mating interface 30 of the connector 12 at which the connector 12 mates with the complementary connector 20. In the exemplary embodiment, the contact modules 28 are oriented generally along vertical planes. But, other orientations are possible in other embodiments. For example, in some embodiments, the contact modules 28 are oriented generally along horizontal planes.

Each contact module 28 includes a dielectric carrier 32 that holds an array of conductors. The carrier 32 may be overmolded over the array of conductors, though additionally or alternatively other manufacturing processes may be utilized to form the carrier 32. Optionally, the array of conductors is stamped and formed as an integral leadframe prior to overmolding of the carrier 32. Portions of the leadframe that connect the conductors are removed after the overmolding to provide individual conductors in the array held by the carrier 32. In addition or alternatively, other manufacturing processes are used to form the conductor array.

The conductor array includes the signal contacts, signal mounting contacts (not shown) described below, and leads (not shown) that connect the signal contacts to the corresponding signal mounting contacts. The signal contacts, the leads, and the signal mounting contacts define signal paths through the contact module 28. Optionally, the signal contacts are arranged in pairs carrying differential signals.

In the exemplary embodiment, the contact modules 28 include ground shields 34 that provide impedance control along the signal paths and/or electrical shielding for the signal contacts from electromagnetic interference (EMI) and/or radio frequency interference (RFI). The ground shields 34 include ground contacts 36 that are configured to mate with corresponding mating ground shields 38 of the complementary connector 20. The ground shields 34 also include ground mounting contacts (not shown) that will be described below. The ground contacts 36, a body 40 of a corresponding ground shield 36, and the ground mounting contacts define ground paths through the contact module 28. In some alternative embodiments, the ground contacts 38 and the ground mounting contacts are formed as part of the conductor array described above.

The connector 12 includes a termination interface 42 where (i.e., at which) the cables 14 are terminated to the connector 12. Specifically, at ends 44 of the cables 14, signal conductors 46 (shown in FIGS. 2 and 3) and ground conductors 48 (shown in FIGS. 2 and 3) of the cables 14 are terminated in electrical connection with corresponding signal and ground mounting contacts, respectively, which are arranged along the termination interface 42. In the exemplary embodiment, forty cables 14 are terminated to the connector 12 at the termination interface 42. Specifically, each of the ten contact modules 28 terminates four cables 14. But, any number of the cables 14 may be terminated to the connector 12. Moreover, other arrangements of the cables 14 along the termination interface 42 are possible in other embodiments. Only some of the cables 14, cable splices 16, and cables 18 are shown in FIG. 1 for clarity.

The electrical cable splices 16 electrically connect opposite (relative to the ends 44) ends 50 of the cables 14 to ends 52 of corresponding cables 18. Opposite (relative to the ends 52) ends 54 of the cables 18 are terminated to another electrical connector (not shown) or directly to the electrical device 24 as is shown in the exemplary embodiment.

Various embodiments of a cable splice 16 may be configured for certain applications. Although shown herein for use with an electrical connector 12, in other embodiments a cable splice 16 is used to electrically interconnect two cables wherein one or both cables is not terminated to an electrical connector (e.g., an embodiment wherein the cables 14 are terminated directly to the electrical device 22). Although shown herein as used with an electrical connector 12 that is similar to electrical connectors of the STRADA Whisper or Z-PACK TinMan product lines developed by TE Connectivity, the cable splices 16 may be used with any other type of electrical connector.

Embodiments of the cable splices 16 may be, but are not limited to being, used with electrical connectors that have relatively high-density arrays of electrical contacts (e.g., a relatively high-density array may have at least 12 or at least 20 signal contacts per 100 mm² along the termination interface 42). Embodiments of the cable splices 16 may be, but are not limited to being, used with electrical connectors that are small-form factor connectors (e.g., electrical connectors configured to be compliant with certain standards, such as, but not limited to, the small-form factor pluggable (SFP) standard, enhanced SFP (SFP+) standard, quad SFP (QSFP) standard, C form-factor pluggable (CFP) standard, and 10 Gigabit SFP standard, which is often referred to as the XFP standard). Non-limiting examples of some applications of the cable splices 16 that may use embodiments set forth herein include host bus adapters (HBAs), redundant arrays of inexpensive disks (RAIDs), workstations, servers, storage racks, high performance computers, or switches.

The assembly 10 may or may not be considered to include the electrical connector 20, the electrical device 22, the electrical device 24, and/or any electrical connector (if included) terminated to an end 54 of a cable 14. A combination of a cable 14, a cable splice 16, and a cable 18 may be referred to herein as an “electrical cable assembly”.

FIG. 2 is a perspective view of an embodiment of an electrical cable assembly 100 of the connector assembly 10 (FIG. 1). FIG. 3 is a cross-sectional view of the assembly 100 taken along line 3-3 of FIG. 2. Referring now to FIGS. 2 and 3, the cable assembly 100 includes a cable 14, a cable splice 16, and a cable 18. As described above, the cable 18 has a larger diameter than the cable 14. The cable splice 16 enables two cables having different diameters to be electrically connected (i.e., spliced) together. In the exemplary embodiment, the cable 14 is 30 American Wire Gauge (AWG) and the cable 18 is 26 AWG. But, each of the cables 14 and 18 may have any diameter. The smaller diameter cables 14 may reduce cross-talk between the adjacent pairs. Moreover, in the exemplary embodiment, the cable 14 is a twinax cable that includes two signal conductors 46, and the cable 18 is also a twinax cable that includes two signal conductors 108. But, each cable 14 and 18 may include any other number of signal conductors in other embodiments. Each of the signal conductors 46 may be referred to herein as a “first” and/or a “third” signal conductor. Each of the signal conductors 108 may be referred to herein as a “second” and/or a “fourth” signal conductor.

The cable splice 16 includes a housing 102 and an electrical ground shield 104. The ground shield 104 is shown in phantom in FIG. 2 for clarity. The housing 102 includes one or more channels 106. Each channel 106 is configured to hold both a signal conductor 46 of the cable 14 and a corresponding signal conductor 108 of the cable 18. The channel 106 is configured to hold the two signal conductors 46 and 108 in electrical engagement with each other such that the two signal conductors 46 and 108 are electrically interconnected. As best seen in FIG. 3, the signal conductors 108 of the larger diameter cable 18 have a greater diameter than the signal conductors 46 of the smaller diameter cable 14. Accordingly, each channel 106 is configured to hold two signal conductors (from two different cables) that have different diameters in electrical engagement with each other. The cable splice 16 thus enables a larger diameter cable (e.g., the cable 18) to be electrically connected (i.e., spliced) to a smaller diameter cable (e.g., the cable 14).

Specifically, the size and shape of the channel 106 is selected to hold the signal conductors 46 and 108 of the cables 14 and 18, respectively, in electrical engagement with each other. The channel 106 may be configured to hold two differently sized signal conductors having a variety of different diameters. As used herein, two structures are “electrically engaged” and in “electrical engagement” with each other when they are electrically connected together via physical contact, solder, a weld, and/or the like. In some embodiments, the channel 106 is configured to hold the signal conductors 46 and 108 in a press-fit arrangement wherein the signal conductors 46 and 108 are pressed together in physical contact such that a sufficient electrical connection is formed without using solder, a weld, and/or the like. In other embodiments, the signal conductors 46 and 108 are soldered, welded, crimped and/or the like together to form a sufficient electrical connection therebetween.

As described above, in an exemplary embodiment each of the cables 14 and 18 has two respective signal conductors 46 and 108. Accordingly, the exemplary embodiment of the housing 102 of the cable splice 16 includes two channels 106, each of which holds a corresponding pair of the signal conductors 46 and 108. But, the housing 102 may include any number of channels 106 for splicing together cables having any number of signal conductors. Each of the channels 106 may be referred to herein as a “first” and/or a “second” channel.

The ground shield 104 includes a body 110 external to the housing 102. The housing 102 of the cable splice 16 may be held by the body 110 of the ground shield 104 such that the body 110 extends at least partially around the housing 102 and the ends 50 and 52 of the cables 14 and 18, respectively. The body 110 of the ground shield 104 thus extends at least partially around the signal conductors 46 and 108 to provide shielding for the signal conductors 46 and 108 from EMI and/or RFI.

To energize the body 110 and thereby provide the signal conductors 46 and 108 with the shielding described above, the body 110 of the ground shield 104 is electrically connected to the electrical ground conductor 48 (e.g., an electrically conductive braid, an electrically conductive foil, and/or the like) of the cable 14. The body 110 of the ground shield 104 is also electrically connected to an electrical ground conductor 112 (e.g., an electrically conductive braid, an electrically conductive foil, a cable drain, and/or the like) of the cable 18. In the exemplary embodiment, the cables 14 and 18 are provided with electrically conductive cable ferrules 116 and 118, respectively, and the body 110 of the ground shield 104 is electrically connected to the ground conductors 48 and 112 via the respective cable ferrules 116 and 118. Specifically, the cable ferrules 116 and 118 are secured around the ends 50 and 52 of the cables 14 and 18, respectively, such that the cable ferrules 116 and 118 are electrically engaged with the respective ground conductors 48 and 112. The body 110 of the ground shield 104 is electrically engaged with the cable ferrules 116 and 118 such that the body 110 is electrically connected to the ground conductors 48 and 112.

In the exemplary embodiment, the ground shield 104 includes spring tabs 120 that project radially inwardly and each electrically engage the corresponding cable ferrule 116 or 118 to electrically connect the body 110 of the ground shield 104 to the ground conductors 48 and 112. In some embodiments, the tabs 120 are configured to engage in physical contact with the corresponding cable ferrule 116 or 118 such that a sufficient electrical connection is formed without using solder, a weld, and/or the like. In other embodiments, the tabs 120 are soldered, welded, and/or the like to the corresponding cable ferrule 116 or 118 to form a sufficient electrical connection therebetween. Each tab 120 may be differently configured (e.g., sized, shaped, and/or the like) from one or more other tabs 120, for example to facilitate accommodating the corresponding larger or smaller diameter cable.

In other embodiments, other arrangements, configurations, and/or the like may be used to electrically connect the body 110 of the ground shield 104 to the ground conductors 48 and/or 112 in addition or alternative to the tabs 120. For example, the body 110 of the ground shield 104 may be crimped around the ends 50 and 52 of the cables 14 and 18, respectively, to bring the body 110 (and/or any tabs 120 that optionally may be included) into electrical engagement with the cable ferrules 116 and/or 118 (in addition or alternative to using any solder, welds, and/or the like). Another example includes forming openings (not shown) within the body 110 that can be welded, filled with solder, and/or the like.

In the exemplary embodiment, the body 110 of the ground shield 104 has a rectangular shape. But, the body 110 additionally or alternatively may include any other size (e.g., relative to the housing 102, the cable 14, and/or the cable 18), shape, and/or the like, which may be selected to provide the signal conductors 46 and 108 with a predetermined ground shielding. Moreover, and for example, the various parameters of the body 110, the housing 102, and/or other components and/or features of the cable splice 16 may be selected to provide impedance control and/or minimize electrical reflections along the cable splice 16. Examples of such parameters that may be selected to provide impedance control and/or minimize electrical reflections along the cable splice 16 include, but are not limited to, the size, shape, and/or the like of the body 110, the size, shape, and/or the like of the housing 102, the relative size, shape, and/or the like between the housing 102 and the body 110, the materials of the housing 102, the amount of air held within the housing 102, the size of the volume of air between the housing 102 and the body 110, and/or the like.

The cable splice 16 optionally includes an electrically insulative covering (not shown) that extends over at least a portion of the body 110 of the ground shield 104 to electrically insulate the body 110. Optionally, the cable splice 16 includes one or more strain relief structures (not shown) that extend over at least a portion of the body 110 of the ground shield 104 and the ends 50 and/or 52 of the cables 14 and/or 18, respectively, to provide strain relief to the cables 14 and/or 18. For example, the strain relief structure may be an electrically insulative sleeve (e.g., a heat shrink sleeve and/or the like) that extends over the body 110 of the ground shield 104 and the ends 50 and 52 of the cables 14 and 18, respectively, to electrically insulate the body 110 and to provide the cables 14 and 18 with strain relief. In other embodiments, the cable splice 16 includes one or more discrete strain relief structures (e.g., a boot and/or the like) that provide strain relief to either the cable 14 or the cable 18. In some embodiments, the cable splice 16 includes an electrically insulative structure (not shown) that does not provide strain relief. Moreover, in some embodiments the cable splice 16 includes a strain relief structure that is not electrically insulative.

FIG. 4 is a cross-sectional view of another embodiment of an electrical cable assembly 200 illustrating an embodiment that does not include cable ferrules (i.e., the cable ferrules 116 and 118 shown in FIGS. 2 and 3 are not included). The cable assembly 200 includes a cable 14, a cable splice 216, and a cable 18. The cable splice 216 includes a housing 202 and an electrical ground shield 204. The housing 202 includes one or more channels 206 that hold a corresponding signal conductor 46 of the cable 14 and a corresponding signal conductor 108 of the cable 18. Each of the channels 106 may be referred to herein as a “first” and/or a “second” channel.

The ground shield 204 includes a body 210 that holds the housing 202 and provides shielding for the signal conductors 46 and 108 from EMI and/or RFI. The body 210 of the ground shield 204 is electrically connected to the electrical ground conductor 48 of the cable 14 and to the electrical ground conductor 112 of the cable 18. Specifically, the body 210 is electrically engaged with each of the ground conductors 48 and 112. In the exemplary embodiment, the ground shield 204 includes spring tabs 220 that project radially inwardly and each electrically engage the corresponding ground conductor 48 or 112 to electrically connect the body 210 of the ground shield 204 to the ground conductors 48 and 112. In some embodiments, the tabs 220 are configured to engage in physical contact with the corresponding ground conductor 48 or 112 such that a sufficient electrical connection is formed without using solder, a weld, and/or the like. In other embodiments, the tabs 220 are soldered, welded, and/or the like to the corresponding ground conductor 48 or 112 to form a sufficient electrical connection therebetween. Each tab 220 may be differently configured (e.g., sized, shaped, and/or the like) from one or more other tabs 220, for example to facilitate accommodating the corresponding larger or smaller diameter cable.

In other embodiments, other arrangements, configurations, and/or the like may be used to electrically connect the body 210 of the ground shield 204 to the ground conductors 48 and/or 112 in addition or alternative to the tabs 220. For example, the body 210 of the ground shield 204 may be crimped around the ends 50 and 52 of the cables 14 and 18, respectively, to bring the body 210 (and/or any tabs 220 that optionally may be included) into electrical engagement with the ground conductors 48 and 112 (in addition or alternative to using any solder, welds, and/or the like). Another example includes forming openings (not shown) within the body 210 that can be welded, filled with solder, and/or the like.

A plurality of the electrical cable splices 16 (shown in FIGS. 1-3) can be grouped together in a single array to facilitate organizing the termination interface of a corresponding connector. For example, FIG. 5 is an elevational view of an embodiment of an array 300 of electrical cable splices 316 configured for use with the termination interface 42 (shown in FIG. 1) of the electrical connector 12 (shown in FIG. 1). As shown in FIG. 5, the cable splices 316 share a common ground shield structure 304 that includes a plurality of ports 306 for accommodating each of the electrical cables 14 that terminate the connector 12 at the termination interface 42.

In the exemplary embodiment, the array 300 includes a rectangular shape and forty cable splices 316 arranged in a plurality of rows and columns to complement the pattern and number of the electrical connections of the termination interface 42. But, in addition or alternative, the array 300 may include any other shape and any other number of cable splices 316 arranged in any other pattern (e.g., a circular pattern and/or the like) to accommodate a variety of differently arranged and configured termination interfaces.

The embodiments described and/or illustrated herein provide an electrical cable splice that enables a larger diameter cable to be electrically connected to a smaller diameter cable.
